High Preference Helical Airborne Antenna Design for UAV

摘要

The mobile communication system, whose most remarkablernadvantages are convenience, stability, and extensibility, has been widelyrnapplied in daily life. Depending on the structure of the mobilerncommunication system, the signals can be stretched through the UAV withrnthe repeater platform, which can help to prove the connection rapidly withrncommunication dead zones. A high performance helical antenna used forrndata transmission on UAV will be design and constructed in present work.rnThere are three main experimental steps. The feasibility evaluation,rnconnection distance and the calculation of receive sensitivity are the firstrnstep. Second, follow the limitations and conditions of UAV to launch thernexperiments. Finally, to use 2-stage tests which were shielded RF AnechoicrnChamber and aviation experimental region, and provide the best controlrnparameter to future modification from experimental data.
